Summary Snapshot on Dashboard - Allow Us to Compare different time periods to evaluate Professional Development.

Now that we have rolled out chromebooks en masse, I would like to collect longitudinal data comparing usage over a period of time.

It would be nice to report out data comparing different time periods (e.g., comparing one week vs. three weeks prior) to evaluate use of devices and impact of Professional Development. This would help justify the PD we are offering and the expense of the technology.
